Brown discharge/spotting at 34 weeks pregnant?!

I'm 34 weeks pregnant with baby no 2, it's been a hard pregnancy this time had a couple of bleeds throughout but everything has been fine.For the past 3 days I've had brown spotting/discharge followed by back pain which comes and goes, the brown blood has had a tiny bit of mucus in but not much.Just wondering if anyone else has had this and everything has been ok.

I would call the maternity assessment unit. I was in an out with bleeding in my second pregnancy which turned out to be from a cervical erosion (so not a big deal) but they still wanted to check me over.

Your symptoms with the back pain are also how my labour started, so again worth getting checked.
